Application July 1, 1947, Serial No. 758,422-

a case in said housing means for receiving heat- 1 ing means therein andfor receiving means for impelling air over said heating means andthrough the clothes retained on said clothes retaining means.

Another object of this invention is to provide timing means associatedwith said air impelling means.

A further object of this invention is to provide a cover means for saidclothes retaining means whereby air may be restricted within certainpredetermined travel.

A further object of this invention is to provide means for selectivelyretaining said clothes retaining means in predetermined, adjustedposition.

Another object of the present invention is to provide means for engagingand retaining said cover means in certain predetermined positions.

Another object of this invention is to provide a portable device of thecharacter described which is both inexpensive, efficient in its intendedoperation and which lends itself well to commercial manufacture.

Ancillary objects and features of novelty shall become apparent to thoseskilled in theart, in following the description of the preferred form ofthe present invention, illustrated in the accompanying drawings,wherein:

Figure 1 is a perspective view of the preferred form of the presentinvention, parts being broken away in section to illustrate details ofconstruction;

Figure .7 is a perspective view illustrating a swivel joint used inconjunction with the present invention;

Figure 8 is a sectional view of the clamp means used in conjunction andforming part of the present invention and taken substantially on theline El-B of Figure 1 and taken in the direction of the arrows, and;

' Figure 9 is a sectional detail of construction taken on the line 9-9of Figure 3 and in the direction of the arrows.

Referring now in detail to the illustrated preferred embodiment of thepresent invention, like reference characters are used throughout toindicate similar elements thereof.

A box-like housing it! having a cover 12 hingedly secured thereto isprovided as a recipient of various components forming the presentinvention. Conventional hinges M are utilized in holding the lid H tothe said housing l0 and suitable securin means are utilized in securingthe hinges in the usual operative manner. It is noted at this point thatthe preferred material of construction is metallic, however, it iswithin the purviewof the present invention to utilize other materialssuch as plastic and the like.

A base frame It is received in the bottom [8 of the said housing Ill andmay be simply rested thereinor rigidly secured, if so desired. A framenieznben' collapsible in nature and generally indicatedat 2 0 is used inassociation with the base frame [6. The'said collapsible apparatus 20 iscomposed of a plurality of substantially rectangular frame members 22which are pivotally secured together substantially intermediate theshorter legs thereof. The said shorter legs 24 and 26 may be seen inFigure 5 wherein this hinged connection is disclosed. A brace member 28extends aoross selected shorter legs, penetrating the inside legs of theframe which happens to be slightly smaller than the associated frame 22and said cross member 28 terminates within the shorter legs of the saidouter frame 22. A Washer 36 serving the purpose of a spacer may beinterposed between the said shorter legs 24 and 26 respectively as shownin Figure 5. Then, the terminal portion of the said shorter legs arehingedly mounted in a selected manner as shown particularly well inFigure 4.

As seen in Figure 7, the corner segments of the frame 22 may haveapertures in a selected base portion 38. Legs 24 are provided withreduced right angular extensions rotatively received in the aperturesand set screw means 60 engageable with the said portion 38 andextensions. 'Ilhis specific structure will be set forth as thedescription proceeds.

A pair of clamp members 42 and 44 respectively are rigidly secured tothe said base frame member 16 by some suitable means such as the rivetmeans 46 disclosed in Figure 9. A pair of hooks 48 is secured to each ofthe said clamp members for the purpose of receiving the lowermost longerside member 59 of a selected frame 22. It can be readily appreciatedfrom an inspection of Figure 1 that the said collapsible frame apparatus20" may be adjusted selectively in vertical positions by utility ofselected hooks 48. Also, as is seen in Figure 3 the said frame apparatus22 may be entirely received within the receptacle or [housing I0.

Reference is now made to Figure 4, wherein there is disclosed a jointutilized throughout certain portions of the collapsible apparatus 20.The terminal portions of a selected frame 22 are provided with reducedshanks 54 which are received in the bore of an adjacent longer leg 34.Thrust bearings 56 may be interposed between a suitable shoulder 58 onthe said reduced portion and terminal portion of the said longer leg 34.Set screw means 60 is employed in suitable apertures preferably havingcountersunk cooperating apertures, for the purpose of providing frictionbetween moving elements. As will be noted from an inspection of Figure 6there is an annular groove 62 cooperating with the said suitable recess.This annular groove 62 is provided about the periphery of the saidreduced portion 54 and received in the terminal portion of the said setscrew means 69 therein.

A case 66 is provided on the base [8 of the said housing l and adetachable foraminous lid 68 is provided thereon. Heating means,preferably electrically operated heated elements are stretched acrossthe said case 66 and are retained there by suitablebrackets 69.

Means for impelling air over said and through said heating means isprovided. This last mentioned means is preferably electric motor means73 having fan blades 14 driven thereby. It will be noted that any numberof motor and blade assemblies may be employed in accordance with thedictates of sound engineering practice. A

conventional timing device, generally indicated at 16 is provided withinsaid case 66 and is associated with the said motor means 13 through theutility of an electrical conduit 18. This timing means 16 is purelyconventional and has associated therewith a usual switch 80.

. As is seen in Figure 1 a cover means 82 is employed over the saidcollapsible clothes retaining means for the purpose of restricting theair to predetermined, prescribed travel. In the collapsed position, asis seen in Figure 3, the said cover means is retained on the upperportion of the said collapsible clothes retaining apparatus 20, throughthe utility of the said clamp device, which is seen "in Figure 8. Thisclamping device 84 consists of a plurality of hooks and a bearing 4member 86 integral therewith. This bearing member 86 has a slot 88therein and a lug, received in the selected shorter legs 24 and 2B,which is slidably received in said slot. This lug 90 may be a simple pinhaving ribs at one end thereof and received in a suitable threadedaperture. Of course, the said clamp 84 may be r0- tated about theshorter legs 24 and 26, and the rotation is limited by contact of thesaid lug 90 against the extremities of the slot 88.

While there has been described and illustrated but a single preferredembodiment of the present invention, it is apparent to those skilled inthe .art, that various changes including omissions,

additions and rearrangement of elements may be made herein withoutdeparting from the spirit of the invention. Accordingly, limitation issought only in accordance with the scope of the following claims.

Having described the invention, what is claimed as new is:

1. A portable dryer comprising a rectangular housing having a base andremovable cover for the top thereof, a drying frame formed of aplurality of intersecting articulated rods interconnecting a pluralityof horizontal rods adapted to assume different levels as said frame isadjusted between its maximum raised level above the base of said housingand its minimum level when the same is in collapsed position fullyWith-5 in the confines of said housing and cover, abutinents mounted onone side of the base of said housing and engaging one of the lowermosthorizontal rods for adjusting the lateral distension of said drying rackand consequently the levels of said horizontal rods, a heating chambermounted on the opposite side of the base of said housing and underlyingthe rack in all positions thereof, said heating chamber containingelectrical heating means therein and acirculating fan for directingheated air upwardly between the lateral boundaries of said drying frame.

2. A portable dryer as set forth in claim 1 embodying a unitary flexiblecovering overlying the top of the drying frame and extending downwardlyalong all sides thereof in its extended position. V I
